As mentioned Greg, this is not a feature of the site. It seems like something is amiss on your end, as nobody else can recreate it. Have you cleaned out your cache and cookies, or tried another browser? Or as others mentioned, run a malware software.
My wife had an annoying thing with using Firefox, in that the screen froze unless she kept the mouse moving. Removing and reloading Firefox did nothing, either did removing all the cookies and cache, but after I ran Malwarebytes and rebooting, this annoying issue went away. I earned brownie points with this.
